Sodium Vapour Lamp transformer by labpro bunsen flame With the help of anSodium Vapour Lamp transformer by labpro High energy efficiency low pressure sodium lamp 35w. This low pressure sodium vapour lamp works better than 99% of the visible output, concentrated in 5889 0 & 5895 a spectra lines. Sodium vapour lamps used for scientific instruments. Sodium vapour lamps are discharge lamps which uses sodium in an excited state to produce light. These lamps are the most efficient electrically powered light source when measured
